The Secret of Chromastone is the forty-second episode of Ben 10: Alien Force.
When Ben catches a cold, he's pleased to see Tetrax, but is caught off guard after he sneezes on him, Tetrax demands Ben give him Chromastone. Tetrax tries to transform Ben into Chromastone, but instead Ben transforms into Diamondhead. Ben doesn't even have a chance to explain what happened to Chromastone when Tetrax attacks him demanding that he handed him over. Tetrax shatters Diamondhead with a weapon and reveals Sugilite inside. Tetrax gives Sugilite a crystal which he absorbs, then Sugilite flies off to Petropia, leaving the other to put Diamondhead back together and transforms back into normal. Tetrax soon explains about why he needs Chromastone. He tells Ben, Gwen and Kevin about Chromastone being the only one to save Petropia, by using that crystal (Sugilite's backup) which contains a crystallized backup of Petropia and its people (which were destroyed by Vilgax).
Ben's situation gets worse when Vilgax shows up, demanding Tetrax to return the crystal Tetrax stole from him. Ben, Gwen, Kevin and Tetrax fight Vilgax until Kevin accidentally tells Vilgax what's going on when Ben's team and Tetrax tried hiding in a secret warehouse in the sewer (which Gwen thinks is disgusting and stupid) but Vilgax finds them because of Ben's sneeze echoing throughout the warehouse. Vilgax flies to Petropia, while Ben, Tetrax, Gwen and Kevin go aboard Tetrax's ship and fly to Petropia. Vilgax soon arrives to Petropia and fights Sugilite, demanding he returns the crystal. Sugilite pleads for mercy, but Vilgax reveals he has none.
Ben, Gwen, Kevin and Tetrax arrive to Petropia, in order to protect Sugilite. Vilgax plucks the crystal off Sugilite, only to discover the crystal's power had been used up, throws it away and flies back to Vilgaxia. A dying Sugilite hands Ben a second crystallized back-up before fading away. Ben then transforms into Diamondhead (revealing that Diamondhead knows what to do with the crystal) and climbs to the top of Petropia to revive Petropia's people. Diamondhead's actions revive both the Petrosapiens and Sugilite, who reveals to Ben that he is Sugilite, Guardian of Petropia, and that Chromastone still remains within the Omnitrix. Tetrax later flies Ben, Gwen and Kevin back to Earth. Ben thanks Tetrax for the ride home. Tetrax mentions it's the least he could do for them. Gwen says that they don't want to hold him back, as he must be anxious to see his friends. Tetrax says that he is, but first he has a score to settle with Vilgax. Ben asks if that's such a good idea, as he's practically invincible. Tetrax just replies "Maybe... Maybe not." And speaking of Vilgax, he has unfortunately caught Ben's cold. The episode ends with Psyphon giving Vilgax a tissue.

- When Kevin says "Don't worry, in space nobody can hear you sneeze", it is a reference to the famous 1979 film Alien tagline: "In space no one can hear you scream."
- Many changes have been made to one particular scene: Tetrax Shard witnessing the destruction of his home planet.
- When Diamondhead revived the Petrosapiens, no female or child Petrosapiens were seen.
- Unlike Side Effects, Ben's alien transformations didn't have their powers badly affected by his sickness. They were just weaker than normal.
